After analyzing the data, they found cats with a secure attachment seemed less stressed during their reunion, compared to cats with an insecure attachment.
They said cats with a secure attachment were more likely to balance their attention between their caregiver and surroundings. For example, they continued to explore the room while also interacting with their owner.
On the other hand, insecure cats showed more signs of stress by twitching their tail or licking their lips. They would also either avoid the person completely or cling to them by jumping on their lap but not moving.
"In both dogs and cats, attachment to humans may represent an adaptation of the offspring-caretaker bond," co-author Kristyn Vitale said in a statement. "Attachment is a biologically relevant behavior. Our study indicates that when cats live in a state of dependency with a human, that attachment behavior is flexible and the majority of cats use humans as a source of comfort."
Overall, they said 64.3% of the animals were categorized as securely attached, while 35.7% of them were insecurely attached.
The percentages remained relatively the same even when the team put the cats through a six-week training course. The goal was to determine whether socialization coaching would significantly alter their initial results.
“Once an attachment style has been established between the cat and its caregiver, it appears to remain relatively stable over time, even after a training and socialization intervention,” Vitale said.
The scientists said they were surprised by their findings and noted this is the first study to prove cats can display attachment styles that are similar to dogs and babies.
“Cats that are insecure can be likely to run and hide or seem to act aloof,” Vitale said. “There’s long been a biased way of thinking that all cats behave this way. But the majority of cats use their owner as a source of security. Your cat is depending on you to feel secure when they are stressed out.”
